To all who@l 'itmafy concern: .l

Be ,'t known that I, ALEXANDER M. HAUCK, a citizen pf the United States, and a resident of Seattle, in the count'yef, King Vand StateA .of Vashin ton', have inventeda new and Improved arrow, of which the followingr is a fiill,'clear,landfexact description.

This invention relat'es to harrows" provided .with wheels 'for cutting or pulverizing the soil oir clods-.lfA

The objectof the invention-is to provide wheels lare inountedfinay 'be moved' toward and from one'another,l in order to vary the .de ree of fineness fwith which theegirth is pu verized.

Th' l invention consists in 'the construction :ind combination of parts, `to bevmore fully ldescribe hereinafter sind xparticularly set forth in he claims. f

Reference `is to be had to the accompany-y ing drawings, forming a )art of this specification, in which similar"` c aractcrs of 'refer- ,e away-to show the wheels; Iin2 is a side ele-` "vat-ion of the harrow, complaete; Fig. 3 is a `ence' indicate corresponding p'arts in all the' views, and in lwhich,

Figurefl' is a plan view,l with parts broken detailview, part-ly in section,` showing the construction f'a wheell and the manner in `which itf is' `inounted nponitsshift'.;A Fig. 4

is a detail view of one of tlie'teeth; zind'Fig. is a vertical detail sectional view. showing comprises ii frame, composed of members 1,-

one of the boxes'for supporting :1 -,shaft andA the manner in which it isinoiintcd upon the frame of t-hellinachme.` In its present i embodiment the harrow 2, 3 and 4, which may be nia'de of angle-iron andY fastened together at the corners of the frame by an' le-plates 6, 7, 8 and 9. "A drawbar 10 may provided with a' hook 11"on oneend for connection witha pole 12. The other end of the draw-bar 10 may be formed with 'a baseliwhch is bolted to the fraine` member 2. truss-rod "15 connects the plates 6 and 7 and extends through-the drawai' 10. The ends of said .truss-rod 15 may be' provided with screw-tlireads for the reception of nuts 16. A chain 18.is provided,

which is 4connected atits endsto the plate's' and 7, and at its central portion to the le 12.

Aplurality of shafts 20, 21, 22 an 23 are journaled inbearings 25,26, 27 and 28 respectively. l Each bea-rin com rises' a centra-l `boss 30, having laters. ly-extendng Specific-ation of Letters 1ate'nt.."l' Patn Appiienon-nied'ifeih-uay 17,1909. serial no. 47s,'ae.

with t liangesl, .iivhichla-re adapted to rest; against frame of the barrow. Each side meinber is provided lwith' slots 32, which receive bolts' 34. Said bolts pass. through the. lianges 31 eea Feb. 1, 1910.

1the under side of' the side members of the.

and through theslots 32 ii-'it-o an angle-platel 35, whichf is adapted to restupon the upperi `side lof the horizontal ortion of the side frames of theha-rrow. nach angle-plate 35l is formed-with ya depending portion 36 on one endv thereof, which` extends across the end ofthe v,boss 30 and may be fastened with bolts or'rvets 100. l-v Said angle-plateacts as a guide to support the shaft held in the bearing blocks, and the. depending portion of said plate acts .to -protectl the ]onrnal from dirt. yEach"angle-plate 35' is formed with an upwardly-projecting lug 38, which is ada ted to be connected -to the operating4 meelJ An oil? h ole'39 maybe provided `or each bearing.` .Y

VEach shaft' isffornied with cylindrical? portions at its ends, Ywhich 'are received within the cylindrical bearin s formed 1n thebosses 30; Ea-ch shaft is ormed at the innerend of the cylindrical portion with -a Each wheel coi'npri-ses two'disks 41, which are arranged to be fastened' together by means of bolts or rivets42. formed withchannels on their inner faces, which receive flattened ends 44 of theteeth 45. The bolts V42 extend through the holes Said disks VareV ianisin, as will beliereinnfter' ex lained.

ycolla-r 40. Oneof these collars may be made integral with' the shaft, sind the other mayl be secuied by means of :i set-screw or. pin.'

46 formed in said flattened portions. The

wheels may be mounted-upon theshafts inl staggered relation, and the wheels on any one shaft may be made to abut one another. A lever v,50 is pivoted at 51 to a plate 53,`

'which is bolted to the frame of the harrow.

A sector-rack 54 is formed on the plat-e 53, and its teeth are adapted to co-act with ahand lever 55 supported by the lever 50. B -inovng the hand lever 55, the position ofythe'lever 50 may-be changed, and then said lever ma'y be locked in its adjusted position in the well known manner. A-liiik l60 connects the lever 50 vwith the lug 38 on the plate 35 connected with the bearing.

25; a link 64 connects the lever 50 with the lug 38 on the plate 35 connected with the bearin 26; a. link 68 connectsthe -lever 50 he lug 38 on the plate 35 connected with the bearing 28; anda" link 70 connects ioo iio

' tho levgii() with the lu c bnnected with the bearin 27.

The lever 50 may be tlplicated on the Vother side of the, machine, so vthat it ma be possible for the operator to move bot levers."simultaneously, in order to have a more even distribution of thepowgi` exerted in moving the shafts:-

Ifdesired, the harrow m be provided with three shafts; one stationary and the others movable. The movable haftswill-be. operatively connected to the operating'j 1ever by means of links, one being attached above the f ulcrum of said lever and one being at-A tached below... 'In' the present embodiment,

Afour movable shafts. are shown, two of the links being attached above the fulcruni of the lever 50, and two being attached below said fulcrum.

A seat'80 ma be mounted upon the cover 52, and the po e 12 may be provided with cross arms, in order that a serlesof liar-rows .may be connected togetherf Brom the construction aboveset forth, it

will be seen that the wheels all rotate in the samedirection, and that while the teeth 4on the front "half ofthe wheel are moving degrees ofevenness with which the dirt-or clods are broken up may be regulated.

Having' thus described my invention, I'

claim as newfand desire to Patent 1. In a hrrow of the type described, the' combination of a frame, a plurality ofbearsecure by Letters ings slidably mounted in said frame on op-4 name to this speclfication 1n the presence of posite sides thereof and one-in front of the other, shafts mounted in the bearings, wheels mounted on -each shaft, and means operatively connected to said bearings for varying the distance between them.

2. In a harrow of the type described, the I g 38 on theplate 35 are moving 1n o posite co bination of frame, ing slidably mounted on said bearings, wheels on Vsaid shafts, a lever, and

elinks connecting said lever and bear' a plurality erbene-one'in front ofY the other,' shafts mounted "in, the

wherebythe .distancebetween the latter may 'Y to approach olirecede from one another.' 4. n a harro'wof the class described, the
